CLYDE A. SNEAD ATTORNEY United States Patent ()ffice 3,242,622 Patented Mar. 29, 1966 3,242,622 ONE PIECE FLASHING STRIP AND GROUND Clyde A. Snead, 1714 W. 80th St., Hialeah, Fla. Filed July 16, 1963, Ser. No. 295,479 1 Claim. (CI. 5294) This invention relates to a one-piece weather tight flashing strip which includes the conventional shield as well as a gravel stop, water deflector and plaster ground, the said flashing unit being adapted for use in the construction of buildings.-

In the past, there have been numerous types of flashing strips for use on the edges of various type roofs for building structures. The present invention discloses a onepiece flashing strip which may be fabricated and readily transported to a job site for a relatively inexpensive installation.

Accordingly, it is an object of this invention to provide an improved flashing strip for use on building roofs which includes an integral gravel strip and water deflector and which eliminates joints and cracks at the edges and underside of roof sheeting, thereby protecting the ends, edges and undersides from the elements and providing a relatively constantdimension between the edge of a completed roof and the outside surface of the conventional wood or stucco fascia.

Another object of this invention is to provide a means by which water draining off the edge of a roof is deflected downwardly towards the ground and away from the underside of the flashing strip or shield and, consequently, the surface of the building.

Still another object of this invention is to provide a means for retaining roof gravel, thereby preventing loss thereof by washing from the edges of the roof.

It is an overall object of this invention to provide a device of the type described hereinbefore which is simple in construction, relatively inexpensive to install and otherwise well adapted for the purposes for which it is intended.

The foregoing objects are achieved by a single formed sheet metal strip designed for attachment to the roof sheeting by tension fasteners, such as nails, the said flashing strip covering the length of a roof margin.

In accordance with these and other objects which will become apparent hereinafter, the instant invention will now be described with reference to the accompanying drawings in which:

FIG. 1 is a transverse, cross-sectional view illustrating a roof and depicting two different types of roof edges which illustrate flashing strips installed in accordance with this invention;

FIG. 2 is an enlarged, partial cross-sectional view of the area designated by the arrow 2 in FIG. 1 which shows the flashing strip installed on an inclined roof;

FIG. 3 is an enlarged, partial cross-sectional view of the area designated by the arrow 3 of FIG. 1 showing the flashing strip installed on a horizontal roof;

FIG. 4 is a partial perspective view of a flashing strip constructed in accordance with this invention;

FIG. 5 is a perspective view which has been broken away for clarity and which illustrates a flashing strip installed (a) in abutting engagement with a wood fascia, on the left-hand side of the figure, and (b) in abutting engagement and used as a plaster ground on the righthand side of the figure;

FIG. 6 is a cross-sectional view of that portion of FIG. 5 designated by the arrow 6 illustrating an installation of the instant invention including the means for fastening it to the roof; and

FIG. 7 is an exploded perspective view showing a typical butt joint installation with a phantom view of associated building structure.

Referring more particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout the different views, and referring particularly to FIG. 1, the numeral 11 generally designates a roof section which is supported by spaced walls 12 and 13, the said walls 'being formed of concrete blocks 14 joined at the top 16 by a tie beam 17 of poured concrete, the said concrete having reinforcing rods 18 disposed longitudinally therein. The roof section or assembly includes rafters 19 and 21, the confronting ends of which abut one another as at 22 and the other end 23 of which may extend beyond the wall 12 or, as shown in FIG. 3, terminate at the wall 13. In the conventional manner, over the framework defined by the rafters, a surface is defined by sheeting material 24 which in turn is covered with a suitable material, such as felt or tar paper 26, following which a bed or a layer 27 of binder an particulate material is applied, such as asphalt and gravel. At the time the concrete tie beam 17 is poured, anchor bolts 28 are customarily embedded in the concrete becoming securely anchored therein upon curing. Anchor plates 29 and 31 are then fastened to the bolts for maintaining the rafters in position. The extending edges of the rafters are finished by a fascia 32 and a flashing strip 41, which will be described more fully hereinafter, is applied along the edge of the roof. The space between the distal end of the rafters and the plane of the wall is customarily finished with an eave member or joist 36.

As is perhaps well known, the elements cause the gravel disposed in the tar base to become loosened and gradually wash away. In order to inhibit this action, it is desirable to provide a weather or flashing strip 41 along the edge of the roof. Referring to FIG. 4, one embodiment of the flashing strip is provided. The flashing strip is adapted to be fastened to the edge of the roof between an anchoring portion 37 and a flange 38 defining a channel there-between. The said portion 37 and flange 38 are joined by a web 39 which extends above and below the respective planes of the anchoring section 37 and the flange 38 forming an upper edge 40 and a lower edge 42. The web 39 is bent back upon itself along the lower edge to meet the said flange 38 forming a double thickness of the web for a portion 35 thereof, the distal end of the double thickness being bent outwardly forming a deflector or drip portion 47. The top edge of the web is bent angularly departing downwardly to the anchoring section 37 forming an angularly disposed gravel stop intermediate the upper edge 40 and the anchoring section 37. The flange 38 is provided with a downwardly extending lip 48 lying in a parallel plane to that of the web.

In use, the flashing strip 41 is positioned along the edge of a roof, the edge of the roof being between the anchoring sectiion 37 and the flange 38 with the web 39 being spaced therefrom. The strip is adapted to be fastened thereto by nails or the like along the anchoring section. The lip 38 is adapted to space the flashing strip at a relatively constant distance from the Wall or fascia of the building and simultaneously to serve as a plaster ground. It is noted that the flashing strip may be used on a sloping roof as in FIG. 2 or a flat roof as in FIG. 3.

Referring to FIGS. 5 and 6, there is shown a flat roof generally designated by the numeral 61 which comprises sheeting material 62 over which a layer of felt or tar paper 63 has been applied. In any suitable manner the roof is fastened as at 64 for support by a wall 66 which may include concrete blocks 67 joined by a tie beam 68. Referring to FIG. 7, the flashing strip there shown comprises a web portion 69 having two right-angularly extending flanges 71 and 72 extending in a common direction, one of the flanges being bent as at 73 forming a downwardly extending lip portion 74.

In use, the flashing strip of FIG. 7 is applied to the marginal edge as shown in FIGS. 5 and 6 with the flange 71 being fastened to the sheeting material and the lip 74 abutting the wall of the structure. As may be seen, inthe right-hand side of FIG. 5, the lip portion is adapted to provide a ground for the plaster in a stucco type construction.

While the instant invention has been shown and described herein in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope of the invention, which is, therefore not to be limited to the details disclosed herein but is to be accorded the full scope of the claim so as to embrace any and all equivalent apparatus and articles.

What'is claimed is:

A flashing strip for use on a roof having a gravel-type roof-covering andan overhang, and in which a substantiallyvvertical portion is disposed inwardly and below said overhang; said flashing strip comprising an elongated,

one-piece element having a uniform cross-section therealong, said element including a planar, roof anchor'section for securernent in the general plane of the roof for receiving the gravel-type roof covering thereon, said planar anchor section intersecting and continuing in an angular portion extending vertically above and outwardly from said intersection for receiving the peripheral edge portion' of the roof covering thereon and forming a generally beveled edge therewith, said angular portion terminating in an upper edge continuing in a generally planar, depending outer Web substantially normal to the general plane 4- '5 of said anchor section and continuing substantially therebelow and spaced outwardly therefrom,"said* outer web terminating in a lower edge continuing in an outwardly directed, reverse-bend portion defining a dripdefiector depending from the lower edge of said web, said drip-deflector being disposed at an obtuse angle to the general plane of said web, said reverse-bend portion continuing in an inner web portion extending substantially parallel to said outer web and terminating in an upper edge disposed intermediately of said outer web and below and outwardly of the intersection between said anchor section and said angular portion, said inner web portion continuing inwardly from the upper edge thereof in a lateral flange substantially normal to said inner web portion and terminating in an inner edge disposed below the intersection of said anchor section and said angular portion and at least outwardly of said anchor section, said flange continuing from the inner edge thereof in a depending lip generally parallel to said inner web and spaced below saidintersection of said'anchor section and said anchor portion.
